Explanation:
The forecast for Venus is cloudy, cloudy, cloudy. Although similar to the
Earth in size and mass,
Venus'
slightly closer orbit to the
Sun create for it a much thicker
atmosphere and a much hotter surface. The thick atmosphere was
photographed above in
ultraviolet light in 1979 by the
Pioneer
Venus Orbiter. Whether or not
Venus has a moon was the center of a
great
controversy in the 1700s and 1800s. Today we know
Venus has no natural satellites.
Venus's extremely
uncomfortable climate was likely caused by a runaway
greenhouse
effect. Could Earth ever undergo
runaway greenhouse
heating like Venus?
